带有日期时间轴的 AmCharts 在 2PM 之后显示 12PM

Question

我有一个带有日期时间类别轴的 chartJson，类别值作为字符串解析为日期时间值。dataDateFormat 提供为“YYYY-MM-DD LL:NN:SS A”，因为我的日期是上午/下午的 12 小时格式。12PM 的值在 2PM 值之后绘制，即使 12PM 出现在 2PM 之前。我怎样才能解决这个问题？

Answer 1

将日期字符串更改为实际日期值。将图表数据分配给变量。将每个日期字符串更改为一个日期，然后将变量分配给图表选项中的数据提供者。将图表数据分配给变量。var chartData = [&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; "value1": "1",&nbsp; &nbsp; &nbsp; "alteredText": "2019-09-20 1...",&nbsp; &nbsp; &nbsp; "key": "2019-09-20 12:22:03 pm"&nbsp; &nbsp; },&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; "value1": "2",&nbsp; &nbsp; &nbsp; "alteredText": "2019-09-20 0...",&nbsp; &nbsp; &nbsp; "key": "2019-09-20 01:24:03 pm"&nbsp;

Answer 2

AmCharts V3并没有支持AM / PM和12小时日期格式dataDateFormat。注意：由星号LL和A和下面的注意事项：* dataDateFormat 设置不支持带星号的格式化代码。图表将无法解析数据中基于字符串的日期中的那些。您需要事先将数据转换为使用 24 小时格式，以便 AmCharts 使用 进行解析dataDateFormat，或者使用像 moment.js 这样的库将这些日期解析Date为 AmCharts 使用的对象。我建议不要Date按照 WhiteHat 的回答中的建议直接使用构造函数，因为规范仅保证ISO8601 或 RFC-2822 时间戳将起作用，而您的格式不太适合。如果您打算在数组上使用 moment，那么以下代码将起作用：[&nbsp; /* your data array */].map(function(item) {&nbsp; &nbsp; return {&nbsp; &nbsp; &nbsp; "value1": item.value1,&nbsp; &nbsp; &nbsp; "alteredText": item.alteredText,&nbsp; &nbsp; &nbsp; "key": moment(item.key, "YYYY-MM-DD hh:mm a").toDate()&nbsp; &nbsp; }&nbsp; })演示如下：var chartData = [];var chart = AmCharts.makeChart( "chartdiv",&nbsp;{&nbsp; "categoryAxis": {&nbsp; &nbsp; "axisAlpha": 1,&nbsp; &nbsp; "gridAlpha": 0,&nbsp; &nbsp; "parseDates": true,&nbsp;
